To all whmn 'it 'ma concern:

Be it known t at I, CARL E. BnooK- Irapsnn, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinols, have invented a certain new and useful Im rovement in ConcreteConstructions, of which the following is a specification. l

This invention relates to reinforced concrete construction forbuildings, bridges and the like, in which metallic."l rods are embed dedin the concrete.

The object of the invention is to provide means by which parts of thebuilding or other structure may be built in sections upon .the groundvorat a point some distance from the finished work and then assembled insuch a way that the reinforcing rods, lying in the same plane andruiming inthe same direction, vrun in practically continuous linesthroughout the structure.

The invention consists in the various component parts of the structurewhich are built upon the ground, and in thel means for uniting theseparts and particularly the horizontul reinforcing rods for the purposeset forth.

The invention also consists in details of construction which will behereafter more fully described and claimed as the specificationproceeds. Y

In the drawings, Figure 1 is a perspective view showing the parts madein accordance with this invention in partially assembled condition; Fig.2 is a plan view taken at the tops of the cross girders illustrated inFig. l; -F ig. 3 is a vertical sectional detail view of the parts inpartially assembled condition, and F ig. l is a sectional detail view on'the line l-l of `Fig. 3, showing the tie member.

In constructing' the device of this invention, a plurality of hollowcolumns or pillars 8 are provided, having projecting from their tops atsuitable points, the brackets l0.

rl`hese columns are preferablyv made upon the ground from concrete builtaround spiral reinforcing wires or bands 19. and vertical reinforcingrods 1l and 22 respectively. As shown the columns are made hollow but assoon as any given column is set up in permanent position the interiorhollow space. is filled with concrete or other similar material 1G, upt'owithin a short distance of the top of the column, thereby leaving atthe top a recess or opening 18. The rods 1l are adjacent to the brackets10 -and have their upper portions bent outlwardly in the portions alongthe lower inclined faces of the brackets thereby reinforcing and'strengthening the brackets. The rods 22, which are between the brackets10, and between each pair of rods 14 extend beyond the upper and lowerends of the column and are screw threaded so that the ends ofcorresponding rods in oppositel'y placed columns may be, j when placedas shown in Fig. 1, united by turnbuckles '24, as shown.l

A plurality of beams 26 are provided' having lower reinforcing rods 28and 30 and the upper hollow recess 32. Thesebeams -are made of concrete,before buildingopera` tions begin and are allowed to thoroughly hardenbefore being put in place, At suitable distances along these lower rods28 and 30 are triangular vertical metallic stil-rups or tie members 3ft,each having its lower member passed under the rods 28 and over the rod30, the apex 36 of the stirrups being, as best seen in Fig. t,slightly'above the top 38 may be passed inside' of the tops of thesestirrups 3l and adjacent to the tops thereof, as best shown in F l and4. The ends of all of the rods 28, 30 and 38 are provided necting lor.locking pin 42 may pass at the cent er of the columns 8, heretoforedescribed.

ln assembling the device, a plurality of columns 8y are set up upon thefoundations of the building at proper distances apart, the beams 24:,previously pre narod, are placed upon the brackets lO o adjoiningcolumns in such a way that, as shown, the end of each beam oppositeanother corre` 'sponding beam at the opposite side of the adjacentcolumn. The loops 40 upon oppoplane, as best seen in Fig. 3, also intoapproximately the sume horizontal plane, .so that the pin 42 may bepassed through them. T he central rods 30 are bent upward, preferably inthe process of making the beams and before assembling begins, to theinclined loops are engaged by the pin #l2 at or near the tops of thegirders. The upper tension rods 38 are put in position with their loopsLl0 also engaged by the pin l2. and in close Contact with the'undersides of the triangular members 3l.. Floor members orslabs 'x43previouslyprepared and hardened are of the U-sha )ed recess 32 so thatanother ro with loops or eyes 40, through which a con position shown inFig. 3, in which their.

site rods "28 are all brought intovone central provided' v vithprojecting hook members 44' also engaging t ese rods 38,-the slabsthemselves resting upon the tops of the beams 26. These iioor f slabsare put in position, as shown in- Fig. 1 and in dotted lines in Fig. 4,so that there is a space 4t6 between them. Another column 8% is thenplaced on top of the girders'upon each previously laced co1- umn 8 asshown and the buck es' 24 are attached to the rods 22` of both thecolumnsv 8 and 8*. The result of the Work thus far done is to assemblethe parts in posit-ion as shown in Fig. l. Then this condition isreached, .the workmen take soft cement fand fill vin the recesses 34andthe spaces 46 over the tops of the beams, the space 18 in the top 8and 8f* so-that to all appearances a pracof the column 8, and all thespace on top of the column 8 and between it and the girders 26 @and theupper column 8, molding the cement to the same diameter, as the columnstically continuous vertical column is thus formed. The best way of doingthis is to apply suitable formers or molds of the same diameter as thecolumns 8 and 8 to the outsides of the columns adjacent to the beamsland then simply lpour the cement or'grout into t-lieabove mentionedspaces and adjacent to these molds. Such molds are indicated in thedrawings by the parts 48Fig,

The holow interior of the column 8at is also filled with cement up to apoint nearv the top so as to leave a space corresponding to space lSincolumn 8. lVhen the cement thus inserted has hardened, any supportingdevices 'which have been used, though few, or more are required, areremoved and al unitary concrete structure is thus formedin which' therods 28 run practically continuously through the structure, as does alsothe tension rod y38, and the compression rods 3U also run continuouslyexcept for the' upward reinforcing bend provided, as shown in Fig. 3,adjacent to each column. The .floor inembers or slabs are pernmnentl`and rigidly connected to the girders an to the reinforcing rods therein,with the result! that all of the 4parts are tied together and a verystrong, rigid and unitary structure is forn'iet'l.

The claims are: 1. In concrete construction, in combinaion with suitablecolumns adapted to sup port girders, radially arranged concrete girdersresting thereon, provided with horizontal reinforcing rods in theirlower portions, an'd tension rods in their upper portions, all `jof4said metallic rods .in all of. the girders upon'a given column beinglprovided with loopsR lying in the same vertical plane at the center ofthe column, a vertical pin at the center of the column passing throughsaid loops and a cement filling `aroi'nid the pin filling the spacesbetween the girders and the column as and for the purposes set forth.

2. A concrete construction comprisin Va column, a pair of Qppostelyplaced ir ersresti'ng upon said column, a pair o reinforcing rodsrunning horizontally of said girders near'their bottoms, loops upon theends of said horizontal reinforcing rods at the center of the column insubstantially the same plane as said rods, another reinforcing rod'nearthe bottom of each girder bent upward near it-s end toform a diagonalbrace, loops upon the ends of said last-men# tioned reinforcing rodlying at ap roxi- -niately the center of the column an near the topthereof, a fourth reinforcing' rod v extending horizontally ofsaidgirders and near 'the topthereof, loops 'at the ends of lsaid rodsin opposite giiders at the center of the column, metallic vstirrupspassing under the irstfincntioned bottom rods and over the opposinggirders resting u on said column,
